DOOR STRIP.

SPECIFICATION forming part of Letters Patent No. 695,054, dated March 1 1, 190 2.

Application filed May 13,1901. Serial No. 60,007. (No model.)

.To CLZZ whom it may concern.-

Be it known that 1, JOHN W. HoUsBERe, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and usefullmprovements in Door- Strips; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in door-strips, and has for its object to construct a strip which will be automatically forced downward upon the weather-strip by the closing of the door and automatically elevated by the opening of the door.

Briefly described, the invention comprises a shaft mounted in brackets secured to the door and carrying a lever adapted to contact with the door-jamb, armscarried by said shaft near each end, spring-pressed arms connected to the first-mentioned arms by a pivot, a plate carried by the spring-pressed arms, and a door-strip carried by said plate, all of which construction, together with its particular operation, will be hereinafter more specifically described and then particularly pointed out in the claim.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like references will be applied to like parts throughout the different views of the drawings, in which- Figure 1 is a front elevation of a part of a door and door-frame with my improved automatic door-strip secured thereto and in the closed position. Fig. 2 is a transverse vertical sectional view of a part of the door and of the automatic-closing door-strip, showing the latter in the closed position. Fig. 3 is a like view showing the device in the elevated position. i

In the accompanying drawings, 1 indicates the door, to the outer face of which is secured by screws or other suitable means a pair of brackets 2, in which is journaled a rock-shaft 3. This shaft has secured thereon near one end a sleeve l, to which is attached a short lever 5, curved at its upper end toward the door-frame 6. Attached to the outer face of this door-frame 6 is a plate 7, with which the free'end of the lever is adapted to contact when the door is closed.

The rock-shaft 3 has secured thereon adjacent to each bracket 2 an arm 8, which may be held against rotation upon the rock-shaft by means of set -screws or tap screws 9. These arms are cut away on one side at their lower ends and have pivoted thereto by a pin 10 the upper ends of a pair of spring-pressed arms 11, the pin 10 extending beyond the one side of the arms to be engaged by the spring, as will be hereinafter described. Secured to the arms 11 is a plate or strip 12, which is cut away near each end and at the center, and secured over these openings or cut-away portions are plates 14, which are provided with slots that are parallel and through which a portion of the weather or door strip is inserted to secure said strip in posi tion. The arms 11 are also cut away at one side at their upper ends to fit with the cutaway ends of the arms 8, the lower end of the latter arms having one rounded corner, as shown at 15, to permit the easy operation of the same. The arms 8 carry a pin or screw 16, upon which is wrapped a spring 17, the one arm or leg of which. is carried downwardly and then secured in the arm 8 by bending its end at right angles, as shown at 18. The other arm or leg of this spring is of greater length and is also extended downwardly and bears against a screw or pin 19 with itsjone face whether the door is open or closed. During the time the door is closed, however, this arm or leg of the spring also bears against the pin 10 with its opposite face, as shown in Fig. 2.

The weather-strip 20 is preferably made of flexible material-such as rubber orthe likeand is provided with tongues whichare inserted through one of the slots in the plates 14c and then back through the other slot to hold the strip 20 in position. In lieu of providing the strip 20 with tongues slits may be out therein and the part of the stripbetween the slits drawn through the slots in the plates to hold the strip in position in the same mannor as is accomplishedby the tongues.

In operation it will be observed that as the door is opened the outward movement thereof will remove the lever 5 from contact with.

the plate 7on the door-frame, and the springs 17, bearing against the pins 19, causes the plate 12, carrying the'door-strip 20, to rise, as shown in Fig. 3, through the action of the springs. When the door is again closed, the arm 5, contacting with the plate 7, operates the rock-shaft to again move the arms to a vertical position, forcing the door-strip down into engagement with the weather-strip of the door, as shown in Fig. 2, in which posi tion the device is held as long as the door remains closed. The opening of the door, however, permits the springs to again break the joint between the arms and elevate the doorstrip, so as to permit free movement of the door.

It will be observed that in the practice of the invention Various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- A door-strip adapted to be forced into position by the closing of the door; comprising in combination, a rock-shaft supported from the door, a lever carried on one end of said shaft for contact with the door-frame, two pairs of arms pivoted together and suspended from the rock-shaft, a door-strip carried by the lower pair of arms, and springs carried by the upper pair of arms and engaging pins in the lower arms to break the joint between the arms and elevate the lower arms and the door strip when the door is opened, substantially as described.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

JOHN W. HOUSBERG.
